418 IBM System Storage DS3500: Introduction and Implementation Guide
Figure 14-123 Run Diagnostics - completed
14.12 Troubleshooting - Prepare for removal
Before you remove a component, the DS Storage Manager software checks to see if another
component should be serviced first. If you can safely remove the component, the Service
Action Allowed (SAA) LED on the component comes on. The types of components that can
be prepared for removal are:
DS controllers
Drives
DS storage enclosure and expansion enclosure power supplies
Expansion enclosure ESMs
1. To access the software tool, select the Advanced Troubleshooting Prepare for
removal menu command. The window shown in Figure 14-124 on page 419 will open.
Attention: Use this option only when instructed to do so by the Recovery Guru (see
section 14.13, “Recovery Guru - Recover from Failure” on page 419) or by your IBM
Customer Support representative. For CRUs that have an SAA LED, after the SAA LED
comes on, you cannot turn it off without removing the CRU.
